This has been discussed (with several filters suggested) on this list
extensively over the past few days. Anyone want to add a FAQ to the exim
website?

(1) create your filter file. It will basically be

    ...
    if (some condition) then
       fail text "you sent what looks like a virus"
    endif
    ...


    (see recent postings for example filters.  Note that what is
     appropriate for one site may not be for another)


(2) Test is using -bF option.  Note that a buglet (or infalicity) in the
    way that reports can give you misleading statements that a message
    caught by the filter "Will be delivered normally".  If you see the
    "fail" text, then the filter will fail the message.


    be sure to test with negatives as well as positives.


(3) Put

    message_filter = /path/to/filter-file


    in the main part of configure


(4) test anything, eg, exim -bt your@???
    just to see that you have a valid configure file and didn't introduce
    a typo


(5) HUP or restart listening daemon.
